Hello,
A while ago I upgraded the European maps on my rns510. They seemed to work fine until I tried to load POI for a supermarket in France. I discovered all the poi had disappeared. Searching the internet has not helped and when I took it to the vw dealer all they could suggest was a sd card which would cost £150.
Obviously I did something wrong when I loaded the maps but I'm not sure what. I've done a factory and hard reset on the unit and this hasn't helped. I do still have the original map disc that came with the car if that would help.
Any suggestions?
